 Modified Files:
        src/sys/dev/raidframe: rf_netbsdkintf.c
 
 Log Message:
 It seems that some SCSI drivers can block while the spinlock on a given
 disk queue is being held.  Work around this by dropping the lock before
 bdev_strategy(), and re-grabbing the lock afterwards.  This is a
 temporary measure until I get to gutting this queue locking code.
 
 There has been some success with this in addressing PR#39993.
 This patch is from Antti Kantee.  Thanks!
